Rounded edges on gallery/summary blocks

Site URL: https://www.thirstforallah.com/en/home

Hey all,

Any idea why safari on my mac won't show the rounded edges on my summary block. See www.thirstforallah.com/en/home/resources/articles . 

On my phone all 4 edges are rounded (in chrome - i use android). On chrome on my mac for some reason the bottom left corner is not rounded, but the others are. 

My CSS coding is as follows:

//grid gallery curved edges//
.slide.sqs-gallery-design-grid-slide .image-slide-anchor {
	border-radius: 5px !important;
}

.sqs-gallery-block-slideshow {
  border-radius: 5px !important;
}

.sqs-block-summary-v2 .summary-thumbnail {
  border-radius: 5px 5px 5px 5px !important;
}

Have you found the solution yet?
